Y Application led July 11, 1919. Serial No.310,112.

. T0 all whom t may concern vented certain new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to new and useful improvements in oil burners, and more particularly, kerosene oil burners used in heating the cooking stove, and the object of this improvement is to provide an oil burner that can be manufactured cheaply, of a simple design, and durable form of construction, that will not quickly deteriorate under excessive heat.

A further object resides in the arrangement and construction of the burner wherein the ports for supplying air to the jet of oil are so arranged with respect to the oil port, that the air will be drawn across the oil jet and unite therewith vto form a proper mixture at a point midway between the ports and a baffle plate, against which the flame is deflected. y

A further object resides in the arrangement of a drain for-directing the oil that may escape from the oil port, in event the flame becomes extinguished, into a receptacle or basin, which is formed integral with the burner, and thus preclude leakage into the ash-box.

A further object resides in the provision of means for rendering accessible the interior of the burner for easy cleansing of the scale that accumulates therein, and for keeping the port, where the oil is released to the atmosphere, from becoming clogged.

- A still further object resides in the form of construction and means of mounting a baffle plate for controlling the manner in which the flame can be deflected.

The invention consists in the arrangement, construction and combination of parts aswill be more fully described in the following specification, illustrated in the accompanying drawings, and finally pointed out in the appended claims.

In the drawings,

Figure 1 is a perspective view of my improved burner, as applied to a kitchen range.

Fig. 2 is an enlarged view of the same detached from the range.

Fig. 3 is a vertical section taken on line 3 3 ofFigJl. v. n,

Fig. l is a horizontal section taken on line 4-4 of Fig. 3.

Referring more particularly to the drawi ings, in which like reference p numerals indicate like parts, the numeral 1 represents an ordinary kitchen range comprising a fire Y box 2, into which my burner is applied. The Ybase 3 of the burner is preferably embedded in a layer of asbestos 4l, or other noninflamlmable material, which covers the bottom of the lire grate, so as to preclude any air from "passage around the base of the burner.

This base 3, as herein shown, is formed with a guard 5 upon its outer sides, forming `a basin 14kV to retain any overflow of oil v that may escape from theport 6 of the burner. This burner consistsv simply of a hollow, elongated-shaped member 7, that is formed integral with the base' 3, having vits ends tapped for thereception of plugs 8.

The port 6, provided in the top of the burner, communicates with thehollow center, and in alinement with this port isa cleaner 9 havinga needle point 10 that extends up through the hollow of the member'` 7, and is adapted to be projected through the-port 6fand 4cleanse the same of any foreign substance that may accumulate andA preclude the passage of oil therethrough.

The member 7 is further formed with shoulders 11 on both sides of the port 6, that are provided with elongated passageways 12 that extend through the base 3 and are open at both ends to vthe atmosphere. Depressions, or troughs 13, are formed in the shoulders 11. on both sides of the member 6 to drain off the oil in the basin 14, that escapes from the port 6, should the flame become extinguished and thus preclude leakage into the ash pan of the stove, where it may become ignited and develop into serious consequences. Y Y

Secured to the member 7, at one end, is a feed pipe 15 that registers withv the hollow center of the member. This feed pipe 15-is adapted to be coiled over the` top of the burner and thence extend to and connect with the oil reservoir 16, placed at some convenient place out of thefway. Y

17 is a baflle plate that is both slidably and rotatably disposed upon the pipe 15,

'tilting or fters Patent, is

centrally the coil, and'this baffle plate V.is

preferably concaved on one side and convexed on the other, the weight being equally distributed with respect toits pivot point, so that the plate will remain stationary irrespective of the position at which it may be tilted. Y

It is obvious that by simply reversing the .faces of this'baffle plate the flame can be downwardly or upwardly, or by sliding it longitudinally upon the pipe l5, the fiame can be deflected to either side, as desired. i Y

The'novel construction and adaptation of projected `this baffle plate as a deflector serves the further function in that it canbe built of sufficient cross sectional -area to throw off considerable heat by radiation. i

.Y VHaving thus described my invention, what I claim -asnew and desire to protectvby Letl. An oil burner of the class described comprising a base plate having a conduit Yformed integral therewith, a port in the upper side of saidiconduit, a feedpipe connected to said conduit and with an oil reser voir whereby `oilV can be delivered to said conduitfand be ejected outwardly through said port and `means for 4supplying air through said base on both sides of said conduit opposite said port to vform a proper mixture' with said oil, and abafle plate rotatably disposed uponsaid lfeed pipe above said port having its opposite faces convexed and concaved respectively and adapted to be causedwto assume any'tiltable position for deflecting thelfiameofsaid burner. ,Y

k2., An oil burnercomprising a base plate I having a conduit formed integral therewith,

a port inthe upper side o f said conduit, a

feed pipe connecting with said conduit and i coiled upwardly oversaid port and thence i' extended to and connected withan oil reservoir whereby oil can be delivered to said conduit and be ejected outwardly through said port, shoulders provided on the opposite sides of said conduit having -slots eX- tended downwardly through said base plate formed integral with said base, a port inthe.

upperside of said conduit, means provided on the ends of said conduit for rendering accessible the interior thereof for. cleansing, means provided on the bottom of said plate adaptedto be projected upwardly through x said port for cleansing, shoulders formed integral with said conduit-on both sides Vthereof adjacent said port having slotseX- ltending downwardly through said base, Y'

channelways provided on the top of said shoulders'at their juncture with said conduit, a feed pipe connecting at onev end with said conduit and coiled over the top of said port and thence extended to and connected with an oil reservoir, and a member'rotatably mounted upon said feed pipe-above said port having its opposite sides convexed and concaved respectively andadapted to remain stationary in any tiltable position whereby the, flame may be deflected in any i direction.
